Paris CDG Express Debuts March 2027

On March 28, 2027, the long-awaited CDG Express will finally launch, slashing the journey between Charles de Gaulle Airport and central Paris to a guaranteed, non-stop 20 minutes.

This is a critical upgrade for U.S. travelers who currently face the 50-minute RER B commute or the unpredictable gridlock of the A1 motorway.

Departing every 15 minutes from 5:00 AM until midnight, the service will run between a dedicated wing of Gare de l’Est (Platforms 2 through 4) and the existing TGV station at CDG Terminal 2.

To coincide with the train’s arrival, the airport is undergoing a “simplification shock” by renaming its confusing lettered terminals to a strictly numerical 1 through 7 system.

This massive logistical overhaul means the maze of 2A, 2E, and 2F is disappearing in favor of a streamlined layout where numbers guide you outside the terminal and letters only appear once you reach the boarding gates inside.

For Americans flying Delta or Air France, the current Terminal 2E will be redesignated as Terminal 5, while Terminal 2F becomes Terminal 6. The current Terminal 3, often used for low-cost flights, will move to the Number 2 spot to follow the actual physical flow of the airport’s access roads.

The new Alstom Coradia Liner trains are purpose-built for the international traveler, featuring level-boarding platforms so you can roll heavy suitcases directly onto the train without lifting, alongside massive dedicated luggage racks and high-speed 5G Wi-Fi.

Every carriage will be equipped with real-time flight tracking screens that display specific check-in desk locations and gate numbers as you travel.

Gare de l’Est itself is being transformed into a high-end airport hub with dedicated departure lounges and a new underground tunnel connecting it directly to Gare du Nord for easier transfers.

While the estimated €24 fare is a premium over standard transit and won’t be covered by standard Navigo passes, it buys you total reliability and a stress-free start to your trip.

If you are booking a flight for Spring 2027 or later, look for these new terminal numbers on your ticket starting this March.
